Abstract
A method, system, and apparatus are disclosed for autonomous lithium-ion battery protection. In particular, the present disclosure teaches a system that provides for automatic protection of lithium-ion batteries from damage due to deep discharge and, in some embodiments, from recharging in low temperatures. The disclosed system employs internal logic, autonomous switches and, in some embodiments, heaters to protect the battery without any need for spacecraft monitoring or control intervention. The system uses one or more dedicated strings of solar array cells to, in some embodiments, preheat, and to recharge the battery. The system is completely self contained in the battery with the only additional interface being for the string(s) of the solar array cells that are used to provide dedicated and reliable power to the system.
